Abstract: A filtration system is arranged to safely vent a storage room into which a fog mixture is introduced. Venting the storage room reduces and/or prevents a substantial increase in the internal pressure of the storage room. To control the pressure differential between the storage room and the ambient air pressure, a venting manifold with an in-line duct fan is used, for example, to exhaust storage room air into the atmosphere. The exhausted storage room air is filtered to reduce the exfiltration of chemicals and/or other contaminants from the environmentally sealed storage room.

Abstract: An apparatus and a method are provided for an air filter cleaning wand for flushing contaminants from an intake air filter of an automobile engine.

An interior of the conduit is in fluid communication with the proximal flange. The distal end portion comprises a plurality of longitudinally aligned vents in fluid communication with the interior of the conduit. Upon passing water through the water hose and into the conduit, pressurized water streams exit the vents along the distal end portion so as to flush contaminants from the air filter. The air filter cleaning wand advantageously is comprised of a material which is sufficiently durable and temperature resistant to retain its configuration during operation when coupled to pressurized water sources.

Abstract: A dust removing apparatus is provided. An air blower performs air blowing in a space. A processor determines a first period in which a user is absent in the space.

A sensor measures an amount of dust collected by performing the air suction in the space during the first period. The processor determines whether or not a usage status of the dust removing apparatus in the space is appropriate based on a comparison between the measured amount of dust collected in the first period and an estimated amount of dust, which is estimated to be collected under a usage condition in which the user is absent in the space, and outputs information indicating whether or not a usage status of the dust removing apparatus is appropriate based on a result of the comparison.

Abstract: An air purifier capable of reducing time required for purification of a room without giving a feeling of discomfort to a human in the room is provided. During operation of an air purifier 1, air drawn from an inlet 3 into a casing 2 is purified by a purification device 7 and the air is blown to the outside from an outlet 4. If a user of the air purifier 1 selects a particular operation mode in which the user designates an air volume, a control device 12 performs air volume maintaining control. In the air volume maintaining control, with a volume of air blown out from the outlet 4 by the air blowing device 5 maintained constant, a speed of the air is varied by an air guiding device 8 based on a status of pollutant detection. Alternatively, the speed of the air is varied by the air guiding device 8 and the volume of the air is varied by the air blowing device 5.

Abstract: An apparatus and method for cleaning contaminated air in an enclosed space, such as a transportation trailer or a shipping container. An air mover in the space circulates contaminated atmosphere from an area of low pressure to an area of higher pressure. The resulting pressure differential is used to draw a reverse, partial air flow through an air cleaning device. The repeated cycling of a portion of airflow results in cleaning of the atmosphere and a general reduction of the contaminant from the enclosed space.
